Sportster Brake Components

Brake Components for the air-cooled Harley-Davidson Sportster, '57-'22. Brakes are the upgrade nobody regrets, and on a heavy bike carrying a passenger they are worth more than horsepower.

What Is In This Collection

Rotors, brake calipers and brake pads, from Performance Machine, Lyndall Racing Brakes, Arlen Ness, Galfer, Hawg Halters and GBrakes.

Sportster Fitment

Sportster covers '57-'22 - XL883, XL1200, Iron, Forty-Eight, Roadster and Nightster. The air-cooled XL is cable throttle. The liquid-cooled RH Sportster is a different motorcycle and does not share these parts - see RH Sportster.

Years that change what fits:

2004 - the Sportster moved to a rubber-mounted frame, which changes a great deal of chassis hardware.
2007 - fuel injection replaced the carburetor across the range.

Getting Brake Fitment Right

Three things decide what fits: your front end diameter, since 35mm, 39mm, 41mm, 43mm and 49mm forks take different caliper mounts; rotor diameter and bolt circle, because an oversize rotor almost always needs the matching caliper or a relocation bracket; and spoke versus cast wheels, as some caliper kits have a separate spoke-wheel version. If a rotor and caliper are engineered to run together, buy them as the set.
